Input magnetic protection devices shall have D characteristic.
*Load leakage currents are added to those generated by the UPS. If loads ith high leakage currents are
present, adjust this value accordingly. It is recommended to adjust the protective device after measuring
the total leakage current ith the UPS installed and operational ith the intended load.
During transitory phases (po er failure, return and voltage fluctuations) short leakage current peaks may
occur. Make sure that the protection is not activated in such cases.
If the loads have a nonlinear characteristic, the current on the mains input, separate by-pass
mains input and output neutral conductors may have a value that is 1.5-2 times the phase value
during operation. In this case, size the neutral cables and the input/output protection adequately.

Cables shall be passed through the hole under the connection terminals.
Make sure that all circuit breakers are “OFF”/”0” before starting ith the installation.
Connections shall be done ith the order belo .
2nd5.1.1 Protective Earth (Ground) Connections
The device shall be earthed for a safe and reliable operation. Connect the PE ground connectors
before connecting any other cable
Input protective earth connection terminal (PE) of the UPS shall be connected to ground ith a lo
impedance connection.
PE terminals of the loads shall be connected to output protective earth terminal of the UPS.
If there is an external battery cabin present, it shall be grounded via battery protective earth terminal of
the UPS.
2nd5.1.2 Input Connection
Bring the circuit breaker on the distribution panel to “OFF” or “0” position before making the
connections
Connect the phases to input (X2) L1, L2 and L3 terminals.
A definite phase sequence is needed for the UPS to operate. If you encounter “IN SEQ FLR” alarm at
start up, decommission the UPS, make the protection devices on the input distribution panels “0”/”OFF”
and interchange any t o phase cable.
Connect neutral to N terminal of X2.
2nd5.1.3 Separated by-pass mains input connection (optional)
Bring the circuit breaker on the distribution panel to “OFF” or “0” position before making the
connections
Connect the phases to bypass (X3) L1, L2 and L3 terminals.
Make sure that the phases have the same sequence ith the input supply.
Connect neutral to N terminal of X3.
2nd5.1.4 External Battery Connection
Do not put the battery fuses into the fuse holder (F5) before operating the equipment and seeing
the “NORMAL” message on the LCD.
Devices ith internal batteries may have dangerous voltages on the battery terminals
To connect external batteries, do the follo ing:

12
S itch the circuit breaker of the external batteries to “OFF” or “0” position.
Connect the (-) pole of the external batteries to the battery (-) terminal,
Connect the (+) pole of the external batteries to the battery (+) terminal,
Connect the midpoint of the external batteries to the battery N terminal.
Danger of explosion and fire if the batteries of the rong type are used.
2nd5.1.5 Output Connection
To enable the short circuit protection feature of the UPS, each load shall be fed over a separate
circuit breaker chosen according to the load current. This may provide quick disconnection of the
short circuited load and operation continuity of the other loads. To obtain maximum protection,
the rating of each individual load circuit breaker shall have the minimum value, hich is enough
to carry the full load current continuously.
Rated apparent and active po er of the loads shall be less than the UPS po er ratings.
Connect the loads to output (X4) Line and N terminals.
2nd5.2 Communication Interface Connections
Related information is given in “communication” section.

13
3Modes of Operation
There are three operation modes, hich differ in the path of the energy flo .
UPS block diagrams and the energy flo path in each operation mode is sho n belo :
When UPS has no separate bypass mains input, bypass line is also fed from the mains input. Thus, if such
a device is in question, mains input shall be comprehended hen the bypass mains input is referred in the
follo ing sections of the manual.
UPS behavior at the start-up is different from the usual operation. The UPS can only operate in bypass
mode during start-up. So, in order for the UPS to start-up, frequency/ aveform/rms value of the bypass
mains voltage shall be in acceptable limits and bypass shall be enabled.

14
After start-up, the follo ing applies:
Operation mode depends on the priority, inverter, rectifier and bypass preferences made by the user and
mains, separate by-pass mains and battery voltages.
Priority and inverter, rectifier and bypass preferences can be set by using the COMMANDS and extra
commands (EXTCMNDS) menus.
If operation in any of these modes is impossible, output voltage ill not be present. In this case, loads ill
not be fed, and “VSECFLR” message is sho n on the LCD instead of operation mode.
3rd1 Bypass Mode
Devices ithout separate bypass mains input, absorb energy from the mains. In devices ith separate
bypass mains input, energy is dra n from the separate bypass mains.
Loads are fed via static bypass line.
Output voltage has the same amplitude, frequency and aveform as the input voltage.
Current dra n by the loads are only limited by the thermal/magnetic s itches over the energy flo path.
Voltage, frequency and aveform of the bypass supply shall be in their tolerance limits, and bypass shall
be enabled for the UPS to operate in this mode.
When the upper provisions are met, the UPS orks in bypass mode in the follo ing conditions:
During the start-up
If the bypass priority is selected
If the inverter is disabled or blocked
In case of a prolonged overload
You can save energy by selecting the bypass priority. Efficiency in bypass mode is higher than the
efficiency in normal mode. If the bypass priority is selected, the UPS ill operate in bypass mode
henever the frequency/ aveform/rms value of bypass mains voltage is in their tolerance limits. If the
bypass voltage goes beyond these limits, the UPS s itches into normal operation.
Bypass mode doesn’t provide perfect stability in frequency/ aveform/rms value of the output
voltage like in normal mode. Thus, the use of this mode should be carefully executed according to
the level of protection required by the application.
Bypass mode doesn’t provide electronic short circuit protection like in normal mode. If a short
circuit or occurs on the output during bypass operation, the thermal/magnetic protection ill act
and all loads ill be deenergized.
Prolonged overloads may cause the thermal/magnetic protection act. In this case, all loads ill be
deenergized.

15
3rd2 Normal Mode
Energy is dra n from the mains input.
Loads are fed via the rectifier and the inverter. The AC voltage at the input is converted to a DC voltage
by the rectifier. The inverter converts this DC voltage to an AC voltage ith a stable sinusoidal aveform,
amplitude and frequency.
Output voltage is sinusoidal and has a regulated amplitude and frequency. It is independent from the input
voltage.
The inverter is synchronized in frequency ith the bypass mains input to enable load transfer to the
bypass supply ithout any interruption, in case of an overload or inverter failure.
Voltage and frequency of the mains input shall be in their tolerance limits, and both the rectifier and the
inverter shall be enabled for the UPS to operate in this mode.
When the upper provisions are met, the UPS orks in normal mode in the follo ing conditions:
If the inverter priority is selected.
If the bypass priority is selected but bypass is disabled or frequency/ aveform/rms value of
bypass mains voltage is not in acceptable limits.
3rd3 Battery Mode
Energy is dra n from the batteries. Loads are fed via the inverter.
Output voltage is sinusoidal and has a regulated amplitude and frequency. It is independent from the
battery voltage.
Battery voltage shall be in acceptable limits and the inverter shall be enabled for the UPS to operate in this
mode.
When the upper provisions are met, the UPS orks in battery mode in the follo ing conditions:
If rectifier is disabled.
If the rectifier is disabled or frequency/ aveform/rms value of mains voltage is not in acceptable
limits.
